Chemical processes are of fundamental importance in the manufacture and processing of building materials. For example, all hardening processes are controlled by chemical reactions. Building protection agents and coatings require complex, often organochemical compounds. Also during their service life, building materials are subjected to chemical stresses and attacks, be it by salt input, leaching or corrosion by different chemical agents.
The lecture and practical exercises aim to combine theory and practice. The chemical properties of the materials are demonstrated and corresponding reactions and changes due to externally attacking or acting influences are shown, analyzed and explained in great detail.
Means and methods to protect surfaces or to improve rheological properties are discussed.
The whole course conveys different material parameters from raw materials, secondary raw materials to highly synthesised materials. Coupled with the different laboratory environments at the WiB students will learn to choose different analytical methods to obtain valuable data and critically examine said data.
Chemical processes of building materials significantly influence the production, processing, and also the utilization phase of a building. Part of the lecture will be:
- Chemical basics concerning air, water, corrosion, inorganic and organic building materials, binders, weathering processes, preservation and reservation methods
- The dependence of material properties on their chemical composition
- Which chemical reactions of external substances distort the balance of building structures
The lecture normally includes lab course work and field trip.
